SHEET LATHING.

Application filed November 4. 1925. Serial No. 66.653.

This invention relates to sheet lathing.

It consists in the novel construction hereinafter disclosed.

An object of the invention is to provide a woven sheet comprising longitudinal and transverse members arranged to provide a woven sheet suitable for use as a supporting member for plaster with provision whereby the longitudinal members may move laterally inrespect of each otherto compensate for contraction and expansion.

it further objectof the invention is to provide means for conecting the adjacent lon -.tudinal edges of the separate sheets so as to form an interlocked area upon which plaster may be supported without subjectthe plaster surface to the influence of strains due to expansion and contraction of the sheets.

Additional advantages of the structure will be apparent from the following de tailed description, taken in connection with the accompanying drawings in which,

Fig. 1 is a view of an area of the lathing including a portion of two adjacent sheets thereof. attached to the studding upon which the same is supported;

Fig. 2 is plan view on the line 2-2 of Fig. 1;

Fig. is an edge view; and

Fig. 4 is a reverse view of the sheet shown in Fig. 1.

In the embodiment of the invention illustrated in the drawing, each sheet of the lathing is shown as comprising a series of longi tudinal strips 1, which it is contemplated shall be made of relatively thin wood. These strips are provided with slits 2 formed therein at spaced intervals. The main body of the lathing sheet is made up of a plurality of the strips 1, the said strips overlapping at their marginal edges, as indicated at 3. Transverse slats 4, in the form of wood strips of slightly narrower Width, are interlaced through the slits 2. The slits in the adjacent strips 1 are formed in staggered relationship so that the strips 4 interlace through the slits in alternate ones of the strips 1, as clearly illustrated in Figs. 1 and i of the drawings.

By reference to Fig. 1 of the drawing, it will be noted that the strips 4 are mainly exposed on the reverse side of the sheet and that said strips are only exposed on the front side of the sheet between the marginal eds? of str and the adiacent slit Lil strip. The effect of this formatlonis to give to each pair of the strips 1 an undulating surface with depressions at the points where the strips 4 extend over the front face of the strips 1 forming cleats in staggered rows for causing plaster applied to the sheet to adhere firmly thereto.

The marginal longitudinal edges may be reinforced byproviding a double thickness of the strips 1 arranged in such way that there are two of the strips 1 at the upper and lower edge of the sheet overlying each other, indicated in Fig. 2 of the drawing, in which event the outer or face strip is provided with a additional slit 5 arranged near the upper marginal edge thereof, said slits 5 being in a staggered relation to the slits 2.

In order to connect the adjacent marginal edges of the separate sheets, key strips 6 may be interlaced between the adjacent sheets.

The sheets are made up of convenient dimensions so that they can be nailed to the supporting studding 7 by nails 8.

By overlapping the marginal edges of the adjacent strips. the strips may expand and contract in a lateral direction without opening any space between the adjacent edges and without cracking the plaster applied to the lathing. This is true because the marginal edge that underlies the marginal edge of the adjacent strip may move relatively without changing the surface formation of the sheets when the same are attached to the studding.

I am aware that the invention may be used for other purposes than for sheet lathing, where it is desired to form a woven wall for such articles as basket-s, packing crates and the like. I am also aware that the material out of which the structure is made is not necessarily confined to wood, although the wood structure provides an extremely satisfactory material for lathing purposes.

I am also aware that the invention may be modified in certain particulars without departing from the spirit and scope thereof, and I do not limit myself, therefore, to the exact structure shown and described; but what I claim and desire to secure by Letters Patent is:

1. A sheeting. the body of which is com posed of a plurality of relatively narrow elongated strips of material having a tendency to expand transversely and each of said strips being provided with slits, and

transverse strips laced into said slits so as to hold the longitudinal strips in assembled relationship with their marginal edges overlapping.

2. A sheeting comprising a plurality of longitudinal strips, each of said strips being provided with slits running longitudinally thereof, and transverse strips laced into the slits in said longitudinal strips so that the marginal edges of adjacent edges of the longitudinal slits overlap.

3. A sheeting comprising a plurality of longitudinal strips having slits therein, said slits being torn'ied in said strips so that when assembled, the slits will be arranged in alternate parallel rows, transverse strips running at right angles to said first-named strips lZIi'ECl into the slits in said first-named strips, and each of said first-named strips having overlapping marginal edges.

l. A sheeting comprising a plurality of longitudinal strips arranged With their adjacent edges overlapping, transverse binding strips laced in assembled relationship with said first-named strips to hold them in adjustment, and marginal reinforcements ineluding supplemental longitudinal strips laced in association with the upper and lower marginal strips.

5. A sheeting comprising a plurality of longitudinal strips arranged with their adjacent edges overlapping, transverse binding strips laced in assembled relationship with said first-named strips to hold them in adjustment. marginal reinforcements including supplemental longitudinal strips laced in association with the upper and lower marginal strips, and means for connecting adjacent marginal edges of the separate sheets by key strips laced into the margins of adjacent sheets.

6. A sheeting comprising a plurality of longitudinal wood strips having slits therein, said slits being formed in said wood strips so that when assembled, the slits will be arranged in alternate parallel rows, transverse wood strips running atright angles to said first-named wood strips laced into the slits in said first-named Wood strips, and each of said first-named wood strips having orerlapping marginal ed es.
